A comparison is made between the electron density maps of the monoclinic and orthorhombic crystal forms of yeast tRNA(Phe) which have been obtained respectively by ourselves and by another group. It is concluded that the molecular structures are essentially the same in both crystals, although the models derived from the maps are not the same. The relation between the two molecular packings is discussed, and it is suggested that the intermolecular contact in the orthorhombic form which is not present in the monoclinic form, may arise through base pairing of the anticodons of neighboring molecules.
对我们自己和另一组分别获得的酵母苯丙氨酸转运核糖核酸（tRNA(Phe)）单斜晶系和正交晶系晶体形式的电子密度图进行了比较。得出的结论是，尽管从这些图推导出来的模型不同，但两种晶体中的分子结构基本相同。讨论了两种分子堆积之间的关系，并提出正交晶系形式中不存在于单斜晶系形式中的分子间接触，可能是通过相邻分子反密码子的碱基配对产生的。
